Editors get a clearer, safer publishing experience: optional two-factor login for organisations, a personal profile page, and a publish note before content goes live.
Page editing is easier to navigate; full path is visible and copyable, aspect fields are grouped more clearly, version history shows useful logbook context without repeating itself, and page search keeps your place in the tree.
Sites built on the foundation theme gain proper multi-level header menus and belts that can pull children from a chosen source page.
